Managing Infrastructure Through Code and Automation

Understanding Infrastructure as Code

IaC Approaches & Patterns

Different IaC approaches suit different use cases. Understanding the trade-offs helps choose the right tool and pattern for your infrastructure needs.

Many organizations combine multiple approaches for different layers of their infrastructure.

What is the difference between Terraform and Ansible?

Terraform is for provisioning infrastructure (creating resources). Ansible is for configuration management (configuring existing resources).

Terraform is declarative and cloud-focused. Ansible is push-based and system-focused. Many teams

Frequently asked questions

What is infrastructure as code?

Infrastructure as Code (IaC) refers to managing and provisioning infrastructure through machine-readable definition files, rather than manual processes. This allows for automation, version control, and repeatability in your infrastructure setup.

What is configuration drift?

Configuration drift occurs when actual infrastructure differs from defined configuration due to manual changes or deviations from the intended state. It’s a significant problem for maintaining consistency and reliability.

Configuration drift occurs when actual i?

Configuration drift occurs when actual infrastructure differs from defined configuration due to manual changes. IaC prevents this by enforcing configuration through code. Use drift detection tools to identify when infrastructure has been manually modified.

How can I detect configuration drift?

Several tools are available for detecting configuration drift, including Ansible's built-in features, Chef InSpec, and specialized IaC monitoring solutions. These tools compare your desired state (as defined in your code) with the actual state of your infrastructure.
